Marine geology

The main interests are in sedimentary processes on the seafloor and gas-hydrates

Pock-marks


Repeated micro-bathymetry measurements of the pockmarks will allow us to quantify the sedimentation and to detect:


  • Their origin and development,
  • Stability over time. 
  • Biological diversity and ecosystems


Interaction between:


  • Gas-hydrates,
  • Methane emission,
  • Slope stability.

Gas-hydrates:


  • Mapping them
  • Quantifying them, 
  • Characterizing their melting process,
  • Characterizing their implications for the slope instability processes (usually in shallow waters).

For mapping the gas hydrate, we need continuous measurements of gas-seepage and identify activities such as thermal vents. This can be done by video-monitoring, geoacoustic equipment, temperature and chemical composition measurements.
